2 numbers are chosen. Person P is given the product of them. Q is given the Sum of those 2 numbers.
On asking what if they knew the two numbers here is what hapnd:
 
P says: No, I don't know the 2 numbers.
Q says: I knew that
P says: Now I know the 2 numbers.
Q says: I also know the 2 numbers.
 
what are the 2 numbers?
choices:
a> 8 11
b> 3 14
c> 7 4
d> 3 5
 
I am not very sure about the last two choices. But I believe the answer is one of a or b.
Can someone tell me how to solve this?
